What further information do we learn about Gatsby?

He advises Gatsby to leave Long Island until the scandal of Myrtle's death has quieted down. Gatsby refuses, as he cannot bring himself to leave Daisy: he tells Nick that he spent the entire night in front of the Buchanans' mansion, just to ensure that Daisy was safe. Gatsby, in his misery, tells Nick the story of his first meeting with Daisy. He does so even though it patently gives the lie to his earlier account of his past. Gatsby and Daisy first met in Louisville in 1917; Gatsby was instantly smitten with her wealth, her beauty, and her youthful innocence. Realizing that Daisy would spurn him if she knew of his poverty, Gatsby determined to lie to her about his past and his circumstances. Before he left for the war, Daisy promised to wait for him; the two then slept together, as though to seal their pact. Of course, Daisy did not wait; she married Tom, who was her social equal and the choice of her parents.
